Default Oxygen sensor harness connector replacement

Does anyone know a part number for a replacement connector/pigtail that goes to the oxygen sensor? This is the connector that is coming off the main harness; it is damaged and it needs to be replaced on my 1986 coupe. It is a single wire connection.

Thanks!

I can't remember the part number, but it's a standard weather-pak single terminal connector that NAPA carries, I've bought tme there before. If you are careful, you can crush the connector shell with pliers and save the guts to just push into the new shell. If you can't find one local, PM me and I'll send you one or two.

I will go to napa tomorrow and pick their brains (and their catalogs) to see if I can find it.

Yup. NAPA carries them. I broke one of my pigtail connectors last summer when I was replacing one of my 02 sensors, too.

I just replaced my pigtail with one from NAPA. They are by far a better parts store than AutoZone, Advance, O'Reilly, etc.

Anyways, for those looking for a part number on this connector, it is ECHOSC100 from NAPA.

Hope this helps someone else in the future!
